Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "agentseal": {
      "command": "npx",
      "args": [
        "-y",
        "agentseal-mcp"
      ],
      "env": {
        "AGENTSEAL_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add agentseal --env AGENTSEAL_API_KEY=your-value -- npx -y agentseal-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "agentseal": {
      "command": "npx",
      "args": [
        "-y",
        "agentseal-mcp"
      ],
      "env": {
        "AGENTSEAL_API_KEY": "your-value"

}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "agentseal": {

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Agentseal safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AGENTSEAL_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

agentseal-mcp

MCP server for AgentSeal. Tamper-proof audit logs for AI agents, using SHA-256 hash chains.

Every agent action is recorded in a hash chain. With this, you can actually prove to your clients that your agent did what it said it did.

Setup

Claude Desktop

Add to your claude_desktop_config.json:

"mcpServers": { "agentseal": { "command": "npx", "args": ["-y", "agentseal-mcp"], "env": { "AGENTSEAL_API_KEY": "as_sk_your_key_here" } } } }

Restart Claude Desktop after saving.

Cursor / Other MCP hosts

Same configuration — add the server with your API key.

Environment variables

Variable	Required	Description
`AGENTSEAL_API_KEY`	Yes	Your API key from agentseal.io
`AGENTSEAL_URL`	No	Custom API base URL (defaults to production)

Tools

`record_action`

Record an agent action to the audit trail. Call this after significant actions to create a cryptographically chained record of what happened and why.

Parameter	Type	Required	Description
`agent_id`	string	Yes	Identifier for the agent (e.g. `research-bot`)
`action_type`	string	Yes	What kind of action (e.g. `email:send`, `file:write`, `api:call`)
`action_params`	object	No	Details of the action
`reasoning`	string	No	Why the agent decided to take this action
`authorized_by`	string	No	Who or what approved the action

Returns a sequence number and SHA-256 hash confirming the entry was chained.

`query_actions`

Look up previously recorded actions from the audit trail. Use this to check what actions have been taken or recall past decisions.

Parameter	Type	Required	Description
`agent_id`	string	No	Filter by agent
`action_type`	string	No	Filter by action type
`limit`	number	No	Max entries to return (default 20)

`verify_chain`

Verify the integrity of the hash chain. Each entry's SHA-256 hash includes the previous entry's hash — if any record was modified, the chain breaks and this reports where.

Parameter	Type	Required	Description
`agent_id`	string	No	Verify chain for a specific agent. If omitted, verifies all entries.

Returns the number of entries verified and whether the chain is intact.

How it works

Each recorded action is hashed with SHA-256. That hash includes the previous entry's hash, forming a chain. Modify any record and every hash after it changes — verify_chain catches it instantly.
